same as normal. dependig on the one you buy, someare 1:1, 1:2 12:1
basically the way it works is for every 1psi of boost it see's it raises the fuel pressure 1psi.. or 1psi:2psi fuel pressure etc.. they say to stay away from 12:1 as its overkill but im just going off what i have been informed. |

either a 1:1 or 1:2 ration will do the job. injectors im not 100% sure on minimums. dan is running 42lb on 17psi. but F6 typhoons run the same injectors as a BA N/A (all models) but run the higher fuel pressure
